The lower ball joints on a Polaris Sportsman are prone to damage from rocks and debris. You need to check them regularly for rips or wear, and replace them as soon as you find a problem.
While the A-arm is off your ATV to replace the ball joint, it's also a good time to inspect and, if necessary, replace the rubber bushings. This guide will walk you through replacing Polaris Sportsman 850XP front lower ball joints and bushings. Watch the video above and print the guide below for reference.
NOTE: The suspension control arms on a Polaris Sportsman 850XP are more commonly known as the A-arms. We refer to them as A-arms in this guide.
Replacing Polaris Sportsman 850 Front Lower Ball JointsStep 1. Remove the front wheel.
Step 2. Remove the lower ball joint bolt from the steering knuckle, and tap the ball joint down and out of the knuckle.
Step 3. Remove the two 15mm lower A-arm pivot bolts securing the A-arms to the chassis.
Step 4. Remove the lower A-arm from the chassis. You'll probably have to use a screwdriver to pry the arms and the rubber bushings from their mounting points.
Clean the lower A-arm if necessary.
Step 5. Remove the circlip from the lower ball joint.
Step 6. Place the lower A-arm and ball joint over a metal collar or piece of pipe with a diameter just big enough to allow the ball joint to be driven out of the A-arm and into the collar/pipe.
Watch the clip below for the portion of the video that covers this step.
Step 7. Use a press to push the lower ball joint out of the A-arm. If you don't have a press, it is possible to drive the ball joint out by hitting it with a hammer, but it's not recommended.
PRO TIP: Placing a large enough socket over the lower ball joint makes pressing it out much easier than pressing directly onto the ball joint itself.
Watch the clip below for the portion of the video that covers this step.
Step 8. Turn the A-arm over, place it back over the collar or pipe, install a new lower ball joint and press it into the A-arm. Once again, it's possible to drive the new ball joint into the A-arm with a hammer, but that method is not recommended.
Watch the clip below for the portion of the video that covers this step.
Step 9. Reinstall the circlip over the new lower ball joint.
Replacing Polaris Sportsman Front A-Arm BushingsStep 1. Remove the four rubber A-arm bushings (two in each arm) and the two metal shafts (one in each arm) that sit inside the bushings.
Step 2. Clean the metal A-arm shafts, inspect them for wear and replace them if necessary.
PRO TIP: Replacing the shafts should only be necessary if the A-arms/bushings have not been greased regularly.
Step 3. If the A-arm shafts are worn, also inspect the lower A-arm pivot bolts for wear and replace those too if necessary.
Step 4. Thoroughly clean the inside of the A-arms where the bushings are housed, and check that the zerk fittings on each arm are clean and working. Replace the zerks if they're badly corroded or no longer work.
Step 5. Lightly grease the new A-arm bushings and install one into each A-arm. Gently tap the bushings fully into place.
Step 6. Lightly grease the A-arm shafts, and install them into the A-arms and the bushings. Next, install the second bushing into each A-arm. Gently tap the bushings fully into place, and center the shafts within the A-arms.
Reinstalling Polaris Sportsman Front Lower A-armsStep 1.
Reinstall the A-arm into its chassis mounts, and reinstall and tighten the two pivot bolts.
Step 2. Connect a grease gun to each A-arm zerk fitting, and pack them both with grease until you can see it just beginning to squeeze out from the bushings.
Step 3. Push the lower ball joint back up into the steering knuckle. Position the groove in the ball joint to align with the bolt hole, and reinstall the ball joint bolt.
Step 4. Reinstall the wheel and you're all done installing the front lower ball joint on your Polaris Sportsman 850XP.
Remember to regularly grease the zerk fittings on the upper and lower A-arms, or you'll be replacing the bushings a lot more frequently than is otherwise necessary. Watch the video below to learn how to grease the zerk fittings on a Polaris ATV.

If you are used to using an ATV, as they say "to the fullest", if you cannot imagine existence without measuring deep puddles and swamps, overcoming hilly terrain, and the thirst for extreme sports was born faster than you, then installing a good powerful winch is just what you need. what you need. nine0016
Installing a winch on an ATV is a simple process, but responsible and requires certain skills and care.
You can read an article about the correct use of a winch on an ATV here.
Winch platform.
Suppose you have already decided on the choice of a winch, then you should pay attention to the mounting of the platform. You can make the platform yourself or purchase it specifically for your ATV model (although you will most likely still have to grind and finish). nine0016
It must be said that the attachment of the winch platform to the frame must be reliable and thoughtful, because all the weight under load will fall on this particular unit.
Winch wiring harness.
For easy cable routing, we recommend that you remove the ATV plastic, this will make your job much easier.
When laying wires, try to keep the power cables as short as possible, this will avoid current loss when the winch is running. If the wires are too long, they should be shortened after laying near the battery and put new terminals in place of the cut.
nine0016
Cables should be tucked into the corrugation to avoid short circuits and direct contact with the ATV frame.
Attention! Wiring should be carried out with the battery terminals disconnected.
Wiring diagrams for winch and control panels.
Connection for control unit, winch and battery.
Wiring diagram for winch control to solenoid.
Winch radio control connections to dual solenoids. nine0232
After installing the winch and wiring, check the winch and control panels for proper operation.
A video that shows in detail the entire process of installing a winch on an ATV:
you can always ask a question or make a suggestion in the comments. I wish you a successful installation of the winch on your ATV, and fewer situations in which you have to use it.
